....in doing so will inevitably remove referenced objects. To reduce the probability of certain objects becoming undetectable garbage, our default mechanism can be extended by the addition of garbage collection driven by the objects themselves. In other distributed systems [Parrington95] Rosenburg92][ANSA91][OMG93] this is typically referred to as orphan detection [Panzieri88] although we term it object driven garbage detection. If lost references are detected (e.g. through the use of periodic keep alive messages) then the objects automatically reduce their reference count for the appropriate ....

Managing ANSA Objects with. . . - Genilloud, Polizzi (Correct)
....comparison and proposed reconciliation of the two models are investigated solely for the purpose of accessing ANSA objects from the OSI world. Therefore, several points, which may seem important to the reader, are not addressed here. This comparison is mainly based on the ANSA computational [7] and engineering viewpoints, for it is at these levels that an OSI ANSA mapping occurs. The two models differ in their primary intended use. The OSI Network Management model is used to describe the management of an OSI system whereas the ANSA model aims to specify a complete objectbased ....

....interfaces are. An interface reference is the name of a particular interface instance (it can be used directly to invoke an operation on that particular interface instance) It is a reliable name; if an object disappears attempts to use a reference to one of its interfaces will end in failure. [5] Selection An object and an interface are selected by the use of a particular interface reference. Interactions Interactions take the form of the execution of a particular operation in a given interface. They are either interrogations with a fixed number of arguments and results (or an ....

....composed of interacting objects. It considers specifications of these systems from five viewpoints : enterprise, informational, computational, engineering, technological. Each of these focuses on particular concerns within a system [3] This presentation will be mainly based on the computational [4] and engineering views, for it is at these levels that an OSI ANSA mapping occurs. 2.1.1 Object model Definition An object is the unit of encapsulation of data, characterised by its state, behaviour and interfaces. Each interface is a group of operations. The set of interfaces of an object may ....
